From the inter-web:
How long does it take for diesel to evaporate?
Diesel fuel is most often a light, refined petroleum product. Small diesel spills will usually evaporate and disperse within a day or less. This is particularly true for typical spills from a fishing vessel (500- 5,000 gallons), even in cold water. Thus, seldom is there any oil on the surface for responders to recover.
Interesting——thanks!
Thanks for a nice dose of reality... I hate liberal/environmental hysteria bullsh*t posts.
